RELEASTNG MEANS AND LEVJELING- DEVICE.

Specification of Letters Patent.

Patented dept. rare.

Application filed February 13, rare. Serial No. 217,006.

of Chicago, in the county of Cook and State of lllinois, have invented certain new and useful Improvements in Releasing Means and Leveling Devices, of which the following is a specification.

This invention and leveling devlce means.

. One of the objects of the invention is to eliminate a relatively large number of parts for performing the functions of releasing the brakes and leveling'the same.

Another object 18 to provide release and leveling device means'which may be ap lied to a railway car truck in various p aces therefor without alteration thereof.

Generally speaking, these and other ob-- jects are accomplished by providing, 111 a "railway cartruck, means interposed between a plurality of brake beams for giving the same a yieldable releasing movement.

Theinvention is illustrated on the accompanying sheets of drawings, in which- Figure l is a fragmentary plan view of a railway car truck embodying my invention; Fig. 2 is a fragmentary side elevation of the same showing end and intermediate car truck portions superimposed upon each other to point out the advantages of my invention; Fig. 3 is a sectional view taken on the plane of line 3-3 of Fig. 2; and

Figs. l to 9, inclusive, are detail sectional views showing various modifications of means for operatively connecting the releasin spring and the brake beam.

The various novel features of my invention will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.

With the ordinary six-wheel truck, twentyrelates brake releasing.

. portions of are arranged difl'erently by the reference character In the same figure T have also shown superimposed upon the end portion of the truck frame, an intermediate portion of the truck frame, the out line of which is indicated by the reference character 11. From this figure it is apparent that where a separate releasing spring was used for each end of each beam, it was quite natural that releasing springs of three or four designs were used in connection with a single truck. To avoid the use of a multiplicity of designs of releasing springs and to greatly reduce the necessary number of releasing springs, l have chosen to provide a single releasing-spring to be used in common with two associated brake beams at each end thereof, said brake beams being arranged upon opposite sides of a given pair of wheels.

The brake beams 12 in this. case are part of a clasp brake rigging, being shown upon opposite sides of a pair of wheels 13, one only of which is shown. Taking advantage of the fact that the height of the din'erent the truck frame over the center of the car wheel axle is the same, I have anchored a single releasing sprin or resilient member l l to the car true directly over the axle of the. car wheels, this spring '14: preferably being secured to the wheel guard of the car frame. Any pair of wheels and axles can be dropped from the truck without removing springs or beams. This single spring, which extends between the beams, in each case hasits ends connected to each of the associated brake beams 12 preferably near the ends thereof, it being understood, of course, that preferably there is a spring 14' at each sideof the truck for each pair of wheels. This releasing spring 14: has a singlecentral loop, which is the part secured to the wheel guard, and has adjacent the brake beams 12 two loops whereby the ends of the spring extend upwardly toward the brake beams, overlap the latter, and are secured thereto by a bolt and nut arrangement 15. This releasing spring 14:, which is located intermediate the associated brake beams, not only serves the function for giving the brake beams areleasing the releasin spring 14 to the frame at thepoint 16, w ich is the middle point of the spring, is to prevent longltudmal shlftmg movement of t e spring 14 and to make ossible the equalization of the releasmg actron. The Wheel guard is chosen as the anchoring support for the releasing spring because it is the handiest place and because its position relative to the wheel axles in each case is constant. These springs are interchangeable, thereby making it possible for any one of the same to be transferred'from one set of brake beams to another without any alterations being made.

In Fig. 5 of the drawlngs I have shown the releasing and levelin spring 14 as having a wedge portion 1? which is drawn toward the web of the I-shaped brake beam 12 and secured to the beam by a bolt and nut arrangement 18. It will be appreclated that the tighter the nut is drawn the eater will be the clamping action between t e end of the spring 17 and the beam 12.

In Fig. 6 I have shown the end of the spring 14 secured to the beam 12 by hooking the end of the spring over one portion of the flange of the beam and pressing a clip 1nto engagement with another portlon of the flange by means of a boltand nut arrangement 19, which secures the clip to the end of the spring 14.

In Fig. 9 the end of the sprlng 1s bent over into engagement with the web of the beam 12 and secured thereto by a rivet 20.

In all of the arrangements thus far described, it will be noted that the spr ng 14 18 directly secured to the brake beam, 1n wh ch case the spring not only serves as a releaslng means, but also as a' leveling means.

By referring to Figs. 4, 7 and 8, 11; W11]. be noted that in each case I have provided the brake beam 12 with a clip 21, the sole function of which is to prevent wear as the result of a sliding movement of the end of the spring 14 with respect to the beam. In Flg. 4 the end of the spring is slightly curved to slidably engage the clip 21. In Fig. 7 the end of the spring 14 is bent to pass over and embrace the beam 12, while in Fig. 8 the end of the spring 14 is looped below the beam 12 in an embracing manner. In the modifications shown in Figs. 4, 7 and 8, the spring 14 serves only as a releasing spring. It is preferable, of course, to secure the sprlngs to the beams, thereby eliminatingthe necessity for the spring clips.

By means of my releasing and leveling device arrangement, many parts are el1m1- nated and but a single design is necessary to meet in an improved manner the various requirements for successful commercial operation. If desired, instead of provlding a single spring, two or more duplicate springs may be provided. The ends of the two springs may meet at a common anchorthe associated beams.

It is my intention to cover all modifications falling within the spirit and scope of the following claims.

What I claim is:

1. In a railway car truck, the combination of brake beams on opposite sides of a pair of wheels, diate its ends and extending between said brake beams for givin the latter a releasing movement when the rakes are released.

In a railway car truck, the combination of brake beams on opposite sides of a 'pair of wheels, and a resilient member anchored intermediate its ends and extending between said brake beams for giving the latter a releasing movement when the brakes are released.

3. In a railway car truck, the combination of brake beams on o posite sides of a pair of wheels, and a single spring extending between and engaging sa1d brake beams for giving the latter a releasing movement when the brakes are released.

- 4. In a railway car truck, the combination of associated brake beams, and a single anchored member located between said brake beams for givin the latter a releasing movement when the brakes are released.

5. In a railway car truck, the combination of a brake beam, and means secured to the wheel guard of the truck directly above an axle for giving the beam a releasing movement when the brake is released.

6. In a railway car truck, the combination of brake beams on opposite sides of a pair of wheels, means extending between said brake beams for giving the latter a releasing movement when the brakesare released, and means for supporting an intermediate portion of said means.

7. In a railway car truck, the combination of associated brake beams, a single member extending between said beams for giving the latter a releasing movement when the brakes are released, and means for proportioning the releasing action of said means on said beams.

8. In a railway car truck, the combination of brake beams on opposite sides of a pair of wheels, and a single spring extending between said beams for giving the latter a releasing movement when the brakes are released, an intermediate point of said spring being anchored to proportion the releasing action of said spring on said brake beams.

9. In a railwa car truck having two or more wheels, bra e beams on opposite sides of each pair of wheels, and a releasing spring operatively connected to and between a set of brake beams on opplosite sides of a pair of wheels for giving t e brake beams a repoint or not, as desired. However, the

and a member anchored intermeimam leasing movement when the brakes are re leased, the releasing springs for all of said pairs of wheels being interchangeable.

10. In a railway car truck, the combination of brake beams on opposite sides of a pair of wheels, and a spring extending between and secured to said beams for glving the latter a releasing movement when the brakes are released and for leveling said beams.

11. In a railway car truck, the combination of brake beams on opposite sides of a pair of wheels, and single continuous means extending between and secured to said beams for giving the beams a releasing movement when the brakes are released and for leveling said beams.

12. In a railway car truck, the combination of associated brake beams on opposite sides of a pair of wheels, and single continuous means extending between and secared to said brake beams for leveling the latter.

13. In a railway car truck, the combination of associated brake beams on opposite sides of a pair of wheels, and a single s ring extending between and secured to said brake beams for leveling the latter.
